After the parts have been screwed tight the cap j is applied to close the top opening.

By this construction it will be seen that the bottom of the cup will be clamped between the machinery part on which it rests and the flange g of the tubular conductor K, and thereby the case is firmly held, and that the lug h prevents the case from being rotated, and said lug is concealed from view. In order to remove the oil-cup, a wrench must be applied to the imperforate conductor-tube K.

The ordinary oil-cups with the threaded integral boss referred to may easily be removed and stolen by an unauthorized person simply revolving the case by hand, so as to unscrew the said boss. My invention prevents this and provides aconstruction that renders it dilficult to remove the oil-eups by any one who is not possessed of a special tool suited f or the purpose.

Having thus described my invention, I claim An automatic oiler for attachment to parts of machinery, comprising a case having an exterior flat bottom provided with an opening and a lug on the under side of said bottom projecting down, said lug to fit in a socket on the machinery part to which the oiler may be attached; a tube having a screw-threaded lower end proj eeting through the said opening in the case-bottom to en gage with a threaded opening in the machinery part to be oiled, and bearing against the upper side of the bottom of the case, said tube having at its upper end a head for the application of a wrench.

I11 testimony whereof I affix my signature in the presence of two witnesses.

\VILLIAM JOHN FERGUSON.
